There is an ongoing global effort to advance emerging perovskite solar cells (PSCs), and
many of these endeavours are focused on develo** new compositions, processing …

The surface of a semiconductor often has a key role in determining its properties. For metal
halide perovskites, understanding the surface features and their impact on the materials and …

Halide‐related surface defects on inorganic halide perovskite not only induce charge
recombination but also severely limit the long‐term stability of perovskite solar cells. Herein …

Because interfacial nonradiative recombination (NRR) has a significant influence on device
performance, the minimization of interfacial NRR losses through interface engineering …

In several photovoltaic (PV) technologies, the presence of electronic defects within the
semiconductor band gap limit the efficiency, reproducibility, as well as lifetime. Metal halide …

Metal halide perovskites have become a popular material system for fabricating
photovoltaics and various optoelectronic devices. However, long-term reliability must be …

Metal halide perovskite nanocrystals (PNCs) have recently garnered tremendous research
interest due to their unique optoelectronic properties and promising applications in …

We propose a new model of defect formation and ion migration at the surfaces/grain
boundaries of lead-halide perovskites, based on ab initio calculations. Inspired by the …

Intrinsic ion migration in the metal halide perovskite (MHP) absorber layer and its interfaces
seriously limits the device stability of perovskite solar cells (PSCs). Despite considerable …

We address the behavior in which a bias voltage can be used to switch on and off the
photoluminescence of a planar film of methylammonium lead triiodide perovskite (MAPbI3) …
